The cemita is a torta originally from Puebla, Mexico. The name can refer to the bread roll it is served on as well.
The cemita, also known as cemita poblana, derives from the city (and region) of Puebla. The word refers to the sandwich as well as to the roll it is typically served on, a bread roll covered with sesame seeds. The bread is made with egg, and resembles brioche. Additionally, the ingredients usually are restricted to sliced avocado, meat, white cheese, onions, the herb pápalo and red sauce (salsa roja). In modern times it has appeared on the streets of New York, Los Angeles, and other cities with Mexican food vendors.
